CLAUDE W. KINDER, OF TIEN-TSIN, CHIHLI, CHINA.

FORCE- SPECIFCATION forming part of Letters Patent No. 377,833, dated February 14, 1888.

Application filed october 14, rese.

To a/ZZ whom it may concern: Be it known that I, CLAUDE W. KINDER, of Tien-Tsin, in the Province of Ghihli, North China, a subject of Victoria, Queen of Great Britain and Ireland, have invented a new and useful Improvement in Force-Pumps, of which the following is afull, clear, and exact descript-ion, reference being had to the accompanying drawings, forming apart of thisspecication, in explaining its nature, in which- Figure 1 is a side elevation of the pump. Fig. 2 is a section upon the line x x of Fig. 4. Fig. 3 is a section upon the line y y of Fig. 4. Fig. 4 is a section upon the line w w of Fig. 1. Fig. 5 is a section upon the line z z of Fig. 1. The invention relates to a forceopump the piston of which is adapted to be operated by a long lever and a long radius-bar, to the end of which the lever is connected, and which radius-bar has a steadying lhorn or arm which enters a hole in a suitably`placed plate, the construction being especially adapted to relieve the piston-rod from a straining or cramping action.

In the drawings, A is the cylinder; a, the piston-chamber; a', the piston. Itis connected with the long lever a2 by the spindle c3, which passes through the gland a, and is connected by the stud or pin a5 with the lever or bar. This lever a.2 is connected at its lower end, a6, to the long radius-bar al, which extends beneath the cylinder, and is pivoted at ce at the other end thereof. It has an arm or horn, a, which extends upward to enter the hole al in the steady-plate au. By this construction of long radius-bar and steady arm or horn the friction of the spindle inthe gland is very much diminished, so that the wear of the gland and spindle are decreased and the piston worked more easily. It will be seen that the horn or arm o.9 keeps the radius-bar steady in spite of its length, and prevents any binding action on the pump-spindle.

The piston-chamber a. is connected at one. end by the port B with the valve-chamber C, and at its other end bythe port B with the valve-chamber C. The valve-chambers C C open into each other at c, (see Fig. 2,) which has the outlet c. The valve-chambers are also PUMP.

sesamo. 216.210. (No modem the inlet-passage and a valve which closes the outlet-passage therefrom. Each set of valves is the same in construction, and one set is well shown in Fig. 3, andthe relation which they bear to each other is represented in Figs. 4 and 5. f

The inlet-valves E, or valves for closing the inlet-passages, each comprise a head, e, having an inclined seat, e2. It has the guiding eX- tension or follower e3 and the stud or spindle which extends upward into a hole,e", in the downward extension e6 from the outlet-valve E. This outlet-valve has a head, el, having the valve-seat'e", which closes against the packing-ring or stationary seat e, and it may have y a spindle, ew," to enter the recess or holeel1 in the cap D. The inlet-valve E has asomewhat greater throw than the outlet-valve E; but as the outlet-valve is made larger than the inletvalve it permits both valves to beremoved upon the unbolting and removal of the cap D, so that the interior of the pump can be easily reached, the valves readily removed, and parts;

repaired.

The air chamber F may be arranged to conl nect with the outlet-passage c, as represented in Fig. 3. Having thus fully described my invention, Il claim and desire to secure byvLetters Patent of the United Statesv The combination of the piston-chamber a, the piston a', the spindle a3, long lever a, the long radius-bar al, to the end of which the lever a is connected, a horn or arm, a, the steadying-plate a, having the hole al, which receives the horn or arm a, substantially as described.
